Amazon adds another chunk of downtown office space

Amazon.com has taken another big chunk of office space in downtown Seattle, according to several real-estate sources.

The Seattle-based tech giant recently signed a 10-year lease for 1915 Terry Ave., which is owned by Seattle Children’s Research Institute. Amazon will occupy the entire 270,000-square-foot building. The building has been mostly vacant for a few years.

Constructed in 1953, the Denny Triangle building is seven stories and spans a half block between Virginia and Stewart streets.
